From 74dd34e6e8bb127ff4c182423154b294729b663b Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Sat, 14 Apr 2007 17:01:15 -0400 Subject: NFS: Added support to turn off the NFSv3 READDIRPLUS RPC. READDIRPLUS can be a performance hindrance when the client is working with large directories. In addition, some servers still have bugs in their implementations (e.g. Tru64 returns wrong values for the fsid). Add a mount flag to enable users to turn it off at mount time following the implementation in Apple's NFS client.
